Predict Outcomes of Collisions - Topic 1 Lesson 2

To play croquet, you hit a ball through metal hoops with a wooden mallet. If your ball touches another player's, you can "send" the other player's ball off course. What will happen when the player strikes the ball with the mallet?

• The ball that is hit with the mallet will compress and then stretch back to move the other ball.

• Energy of motion will travel through the ball that is hit, and the other ball will move.

• Sound energy will travel through the ball that is hit with the mallet, but neither ball will move.

• Energy of motion is transformed into sound energy, and the balls will not move.

Cole performed an investigation. He made this table of data. What question was Cole most likely investigating?

• Which ball can be thrown farthest?

• Why do some balls bounce more than others?

• Which ball needs the most energy to collide?

Cole performed an investigation. He made this table of data. Which conclusion is best supported by the evidence in the table?

• The baseball compressed and stretched the most.

• The golf ball has the greatest mass.

• The table tennis ball compressed and stretched the least.

• The basketball takes longer to bounce than the other balls.

Look at the picture. What occurs when the bat makes contact with the ball. Select all that apply.

• Energy transfer causes a change in motion.

• Chemical energy is transformed to energy of motion and heat.

• Some of the ball's energy of motion is transformed into heat.

• Sound energy is transferred to the surroundings.

Look at the picture. Select the statements that are correct statements. Choose two correct answers.

• When the snowball and wall collide, the change in the snowball's speed is evidence for a change in energy.

• When the snowball and wall collide, there is no energy transfer because the snowball falls apart.

• When the snowball and wall collide, the energy of motion of the snowball does not transfer to the wall.

• When the snowball and wall collide, the energy of motion of the snowball is transferred to the surroundings and to the chunks of wall that spread out.
